SOLIJEBLESS PIN.

Application filed September 8, 1927. Serial No. 217,392.

6 give the article an attractive and ornamental appearance, and havingsecuring means for attaching the article to a hat or the like, the wholebeing constructed without the use of solder. 1

A further. object of my invention is the construction of an ornament ofthe class described of an extremely rugged construction which will noteasily become broken.

A still further object of my invention is 16 the accomplishment of theabove at a great saving of manufacturing cost.

A still further object of my invention is the utilization of a portionof a ewel setting as a means for securing the pin member to 20 theornament.

A still further object of my invention, is the utilization of a portionof a jewel setting as a means for securing together the various parts ofthe ornament.

The invention will be specifically described with reference to theaccompanying drawings, which form a part of the specifi cation, and inwhich:

Figures 1, 2 and 3 represent front, side and back views of an"ornamental pin embodying the features of my invention.

Figure 4 represents an enlarged crosssectional view taken on the lines4-4 oi: Figures 1 and 2, showing certain important details ofconstruction.

In the drawings, 1 and 2 represent body portions of the ornament whichmay be of any preferred shape and of suitable material. These bodyportions are provided with holes or perforations 3, which may be placedin any relation to each other, and to the body portion to make anydesired design.

Jewel settings 4, provided with jewel retaining means 4 and with tubularshanks 5, are adapted to be inserted into theperforations 3, and haveexpanded portions 6 behind the body portions 1 and 2. It will be seenthat this tubular shank function of a tubular rivet.

A securing means, in the present instance shown in the form of a pin 9,has a portion such as the coiled head 10, surroundlng the' shank 5 of asetting, and said shank has its portion 6 expanded over said coiledhead. It is to be understood that my invention is not restricted to thisparticular form of securing means, except as limited in the appendedclaims. Obviously, the construction is a very simple and rugged one,since it enables ready assembly of the ornament body and its securingmeans without the use of solder.

The ornament may be made up of a plurality of body portions, and thepresent embodiment shows two portions 1 and 2, having superimposedportions with aligned perforations through which is extended the shank 7of a jewel setting, expanded behind the body portion 2, thereby securingtogether the two portions 2 and 3. Thus the setting serves the dualfunction of mounting the jewel upon the body and uniting the two bodyportions, both results being obtained without the use of solder.

It will be understood, of course, that numerous variations may be madein the illusperforms the hated structure without departing from theinvention, which is defined in the following claims.

I claim:

1. In an article of jewelry,

a perforated body portion,

a jewelsetting having a tubusaid shank then being lar shankextendingthrough one of said perforations and behind the said bodyportion, securing means for the article having a.

coiled portion surrounding said shank behind said body 'portion, saidshank being expanded over said coiled portion and thereby clamping thebody portion, shank and pin against relative movement.

2. In an article of jewelry, a perforated body portion, a jewel settinghaving a tubular shank extending through one of said perforations andbehind the said body portion,

a pin having a coiled portion surrounding hind said body portion havinga part ex- 10 said shank behind said body portion, sai tending aroundthe extended tubular shank shank being expanded over said coiledporbehind said body portion, said shank having tion and thereby clampingthe body portion, its end expanded over said part of the pin shank andpin against relative movement. and thereby clamping together thesetting,
